The last date of the last mil was 12-31-99

The first date of the current mil , also the first day of the last decade, was 1-1-00

From 1-1-00 through 12-31-09 is ten years.

But, then, you already know that, you simply choose to define "decade" as starting 0n 1-1-01.

One could just as easily start a decade on 3-11-04, and count ten years, but it does conform with what is accepted, by most people anyway, as the standard definition of the term when used in denoting 10 year periods with the second unit being the same in a four figure year date.

Rock on, and Happy New Year, regardless.

Now, I think I will go for a ride, the sun just came out. :-)

The 20th century and the 2nd millennium most definitely ended on 12/31/2000. there was no year “0” so each century had to have 100 years (By definition); to do it must begin with year 1 and finish with the end of year 100. This is true whether year “1” is the year 1801, 1901 or 2001. The century began with the year 2001 as did the first decade. The decade will end when its tenth year ends; that’ll be on 12/31/2010.
